I'll procrastinate tomorrow.
Naw, I curl. I don't fold.
Oh i know this one.
You had a update utility going for your mainboard/computer vendor that automatically updates to the newest drivers and such.
well a new bios update was released, and it auto flashed your bios, and your processor wasn't supported on that bios release.
happened to me with my athlon 64X2 6000+ 65nm that needed a Beta bios to function correctly and the MSi auto updater flashed my bios to the newest standard one.
beoyatches took me 2 weeks to find a older X2 4400+ to borrow for a temp cpu swap
